The Knowledge Project

The Knowledge Project is an online data hub where we regularly post data that tracks how effectively New York City's criminal justice system is fighting crime and reducing unnecessary incarceration. This information gives every New Yorker a window into what is working and what needs to be improved.

The Criminal Justice Indicator Report assembles data from across the system and over time to provide insight into how well the criminal justice system is fighting crime and reducing unnecessary incarceration.
